crypto: amlogic - Remove kcalloc without check 

There is no real point in allocating dedicated memory for the irqs array.
MAXFLOW is only 2, so it is easier to allocated the needed space
directly within the 'meson_dev' structure.

This saves some memory allocation and avoids an indirection when using the
irqs array.
